Rafał,

        I have swapped drives again and updated all of the files in:

http://www.3111skyline.com/download/linux/radeonhd/downclock/

        Note: I added a timestamp to the end of the filenames so they won't get 
overwritten. Example:

15:18 nirvana:/srv/www/download/linux/radeonhd/downclock> ls -1
Xorg.0.log.20151550
Xorg.0.log.old.20151550
Xorg.1.log.20151550
Xorg.1.log.old.20151550
xorg.conf.20151550

        The log now shows that ForceLowPowerMode was used to set the clock at 
100000 
Mhz. The heat is reduced, but not by as much as I had hoped. Originally I had 
tried to set "LowPowerModeEngineClock" "50000", but when X started, the 
screen was wildly distorted and "stretched?" so that the kdm login was at the 
far right side of the screen.

        Can I just pick a number that isn't a direct multiple/factor of the 
full 
power clock of say 70000?

        Funny, I don't notice any performance difference between the clock at 
400000 
or 100000. Let me know what else I can send you. Thanks again!
